Abstract: Systems and methods for performing handover coordination between base stations are disclosed. In a first embodiment, a method is disclosed, comprising: receiving, at a base station, a first serving cell signal measurement and a first neighbor cell signal measurement from a particular user equipment (UE); sending an adjustment message, from the base station to the UE, containing a cell-specific offset of the serving cell and a cell-specific offset of the neighbor cell in a reporting threshold based on at least one handover adjustment factor received from a coordinating node; receiving, at the base station and subsequent to adjusting the cell-specific offsets, a second serving cell signal measurement and a second neighbor cell signal measurement; and deciding whether to trigger a handover event based on the first and the second serving cell signal measurement and the first and the second neighbor cell signal measurement and the cell-specific offsets.

Abstract: A method for topology hiding is disclosed, comprising: receiving, at a gateway, the gateway positioned between a core network and a radio access network, a configuration information request from a base station; analyzing, at the gateway, a topology of the radio access network, the radio access network including the base station; grouping, at the gateway, the base station into a first group based on the topology; sending, from the gateway to the base station, a grouping message to indicate that the base station be placed in the first group; and terminating connections from the core network to one or more base stations in the first group at the gateway as a back-to-back proxy, thereby hiding the topology of the radio access network from the core network.

Abstract: A method is disclosed for avoiding unnecessary keepalive data transfers, comprising: receiving, at an upstream TCP connection endpoint in a radio access network (RAN) from an operator core network, an Internet Protocol (IP) packet; performing, at the upstream TCP connection endpoint, shallow packet inspection on the IP packet; and forwarding the IP packet to the downstream TCP connection endpoint in the RAN if the IP packet is not a keepalive packet, based on the performed shallow packet inspection. The upstream TCP connection endpoint in the RAN may be one of a nodeB, an eNodeB, a base transceiver station (BTS), a coordinating server, and a mobile edge computing (MEC) gateway. The downstream TCP connection endpoint in the RAN may be one of the nodeB, the eNodeB, or the base transceiver station (BTS).
